1 Introduction and motivation
Animal Crossing: New Horizons is a life simulation video game developed and published by Nintendo for the Nintendo Switch. It was released worldwide on the 20th of March 2020. Since it’s inception the game has had an astounding world-wide reception With over 22 million copies of the game being sold in just 5 months.
In the animal crossing world a player takes the role of a customized human character who moves to a deserted island and carries out various activities such as gathering and crafting items, fishing and bug hunting in a village inhabited by various species of animals. Each of these animals called villagers in the animal crossing world, have their own name, gender, birthday, personality, favourite song and their own catchprhase. The items used in performing different tasks in the animal crossing belong to different categories and are also priced at different buying and selling values.
Although it has been 5 only months since the game was released worldwide, it has been gaining alot of attention from both players and critics. Even non-players may find the concept of this game well designed and interesting.
THe motivation for choosing Animal Crossing in the analysis is to attempt to understand the reason for the immense popularity of the game using user and critic reviews and features within the game (such as the villagers and the items).
Therefore, the following is an analysis of the villagers and items used in the Animal Crossing world and the views of the players and critics about the game.
2 Data description
The dataset used for this analysis was retreived from TidyTuesday; a project aimed at allowing individuals to practice their data wrangling and visualization skills through the use of real-world data sets.
The retreived dataset consisted of four sub-datasets; ‘villagers’ and ‘items’ datasets containing data about in-game characters and items, and ‘user reviews’ and ‘critic reviews’ datasets contatining data about user and critics reviews on the game.
The ‘villagers’ and ‘items’ datasets have been originally retreived from VillagerDB, which is a project aimed at making data about Animal Crossing available and easily accessible, while the user and critic reviews have been originally retreived by scraping the Metacritic website.

Methodology
=======3 Data Exploration and Wrangling
3.1 Handling Missing Values
It’s interesting how the buying value of22.21% of the items are missing. In order to analyse this further, the percentages of missing buying values of each item category was calculated.
Figure 3.1: Percentage of missing buying values in each category of items
Figure 3.1 states that all buying values of fish, fossils and seashells are missing.
Further research claimed that fish, fossils and seashells can not be bought, which explains the missing buying values. A blog on Animal Crossing states that fish can only be acquired by fishing and can not be bought (“Animal Crossing: New Horizons Fish Guide: How, When and Where to Catch All the Fish” n.d.). Further, a fan page on Animal Crossing states that fossils can be dug up and seashells collected (“Animal Crossing Wiki” n.d.). The rest of the missing buying values too were attributed to be due to the inability to purchase the items in the Animal Crossing World.
The columns with over 80% missing values were dropped from the analysis due to the inabiility to impute values accurately.
3.2 Currency conversion
The buying and selling currencies of items in the animal crossing world were expressed in two currencies; Bells and Miles. For simplification of the analysis all buying and selling prices were converted into Bells.
The Nintendo guides states that a Bell Voucher can be bought for 500 Nook Miles, which can thereafter be exchanged for 3000 Bells in the Animal Crossing world . Therefore it was assumed that each Mile equated to 6 Miles in the currency convesion.
4 Analysis and findings

=======4.3 What do the users say?
The analysis of user feedback on Animal Crossing uses 2999 reviews published by users on Metacritic from 2020-03-20 - 2020-05-03
Figure 4.2 is a plot of the trend of user reviews on Metacritic over time.
Figure 4.2: Trend of user reviews
The astounding reception of Animal Crossing: New Horizons since its world release on the 20th of March 2020 is justified by the number of daily user reviews it has received. Figure 4.2 shows a huge spike in the number of reviews on the 24th of March 2020, lasting till about the 26th of March 2020, which may be attributed to the world release of the game on the 20th of March 2020. The number of reviews there after remain consistent other than another smaller spike around the 28th of April 2020.
Figure 4.3 shows the most common words in the user reviews for the game. The words ‘game’, ‘island’, ‘switch’ and ‘play’ are the most common words in the user reviews and doesn’t show a direct positive or negative significance based on them.
Figure 4.3: The most used words in the user reviews
The user reviews also includes a score from 0-10, where 0 is the lowest and 10 is the highest. Figure 4.4 is a plot of the disctribution of scores ranging from 0-10.
Figure 4.4: Distribution of user review scores on Animal Crossing: New Horizons
Most users score the game as a 0, while other users score the game as a 10. Almost all user scores are distributed to the two ends of the range of scores with very little reviews scroing the game a 5, 6 or 7. With the sudden hype about the game in the recent past, the low review scores seem questionable and may even thought of as the default score attached to a review if not explicitly stated. Therefore, it might be interesting to calculate the sentiments of the user reviews and relate them to their respective scores, to identify any correlation among them.
A sentiment score between -5 and +5 are given to each user review, where -5 indicates a highly negative sentiment and +5 indicates a highly positive sentiment.
Figure 4.5 is a boxplot summarizing the sentiment scores of all 2999 from 2020-03-20 - 2020-05-03.
Figure 4.5: Summary of sentiments of user-reviews
The boxplot in figure 4.5 states that the overall sentiment of the user reviews to be just slightly positive at 0.4, which is surprising as it would’ve been expected to be much higher with the recent popularity it has gotten. Most of the sentiments of the reviews also lie within a range of -1 to +1, which may indicate to us that Animal crossing isn’t enjoyed by all and there are as many users dissatisfied by the game or disliking the game as those enjoying it.
The mean sentiment score of each review against its review score is plotted in figure 4.6.
Figure 4.6: Mean sentiment score of reviews against its review score
The distribution of points over the plot signifies no clear relationship among the sentiments of the review text and score.
4.4 What do the critics say?
In the analysis the viewpoint of critics on the Animal Crossing: New Horizons game, reviews published by 107 critics such as Forbes, Telegraph and Nintendo Life from 2020-03-16 - 2020-05-01 are used.
Figure 4.7: Trend of critic reviews
Figure 4.7 represents the trend in the number of critic reviews over time. Most critics have reviewed the game on the 16th of March, just before the world release of the game, while a smaller number of critics have made reviews in the days following that.
Since critics have the ability to influence people through their comments, it might be interesting to see the most used positive and negative words in their reviews.
Figure 4.8: The most used positive words by the critics
Figure 4.9: The most used negative words by the critics
Figure 4.8 shows the most used positive words in the critic reviews while figure 4.9 shows the most negative words. By direct observation of the number of terms in the two word clouds, the positivity seems to overpower the negativity in the critics reviews.
Figure 4.10 is a further breakdown of the words used by critics in their reviews, based on different emotions portrayed.
Figure 4.10: Break down of words used by critics into different emotional categories
As per figure 4.10, most words used in critics reviews are positive, and resonate the emotions of trust, anticipation and joy. A very few words used in reviews resonate the emotions of disgust, fear and anger, concluding an overall positive response from critics on the Animal Crossing game.
The scores given by the criitcs range from 0-100, 0 being the lowest and 100 being the highest. Figure 4.11 shows the disribution of these scores over critics reviews.
Figure 4.11: The distribution of critics scores on Animal Crossing- New Horizon
It’s interesting how a significant percentage of the reviews score the game above 90, while all of the scores are above 70. Comparing figure 4.4 and figure 4.11, all the critics seem impressed with the game while the users have mixed reviews.
